SSL certificate from QNAP NAS

Hello,

I’m new to Passbolt and I have the following problem.
I use a Passbolt Docker on my QNAP NAS and have already set up a certificate on my NAS.
With Passbolt, however, the www.passbolt.local certificate is still displayed, although I have made a Manual HTTPS configuration on Docker.

My config

version: '3.9'
services:
  db:
    image: mariadb:10.3
    restart: unless-stopped
    environment:
      MYSQL_RANDOM_ROOT_PASSWORD: "true"
      MYSQL_DATABASE: "passbolt"
      MYSQL_USER: "passbolt"
      MYSQL_PASSWORD: "P4ssb0lt"
    volumes:
      - database_volume:/var/lib/mysql

  passbolt:
    image: passbolt/passbolt:latest-ce
    #Alternatively you can use rootless:
    #image: passbolt/passbolt:latest-ce-non-root
    restart: unless-stopped
    depends_on:
      - db
    environment:
      APP_FULL_BASE_URL: "https://weinkeller.site:4433"
      PASSBOLT_SSL_FORCE: true
      APP_DEFAULT_LOCALE: "de_DE"
      DATASOURCES_DEFAULT_HOST: "db"
      DATASOURCES_DEFAULT_USERNAME: "passbolt"
      DATASOURCES_DEFAULT_PASSWORD: "P4ssb0lt"
      DATASOURCES_DEFAULT_DATABASE: "passbolt"
      PASSBOLT_META_DESCRIPTION: "Passwort Manager"
      PASSBOLT_AUTH_LOGIN_TOKEN_EXPIRY: "15 minutes"
    volumes:
      - gpg_volume:/etc/passbolt/gpg
      - jwt_volume:/etc/passbolt/jwt
      - /etc/passbolt/certs/certificate.key
      - /etc/passbolt/certs/certificate.crt
    command: ["/usr/bin/wait-for.sh", "-t", "0", "db:3306", "--", "/docker-entrypoint.sh"]
    ports:
      - 8080:80
      - 4433:443
volumes:
  database_volume:
  gpg_volume:
  jwt_volume:

Thanks and have a good day!
